> Tech folks drastically overestimate how much the average person cares about privacy.

This is old thinking. In the 90s and 00s it was miraculous to trade in a little privacy for some awesome free service on the internet. Google, Facebook and others became huge, and everyone has been influenced / manipulated by them and people are getting tired of having a family dinner conversation next to their smart speaker and seeing ads for six weeks for Depends diapers because someone told a bad joke at the dinner table.
